In order to make the above-mentioned features and advantages of the novel creation more comprehensible, embodiments are described below in detail with the accompanying drawings as follows.

FIG. 1 is a perspective view of a golf putter according to an embodiment of the present invention. Referring to FIG. 1, the golf putter 100 of this embodiment includes a shaft 110 and a head 120. The head 120 is connected to the shaft 110 and includes a head body 122 and a sensor 124. The head body 122 has a shot line 122 a. When the user swings the golf putter 100 to hit the ball, the hitting line 122a can be aligned with the center of the golf ball to accurately perform the hit. When the user swings the golf putter 100, the mass points at different positions of the head body 122 will have different centripetal accelerations due to different distances from the center of rotation of the swing (the further away from the center of rotation, the more the centripetal acceleration will be The position of the center of gravity of the movement is related to the acceleration of its mass points, so the center of gravity of the movement of the club head body 122 is shifted in the direction D away from the swinger due to the swing motion. It should be noted that the above-mentioned and later-mentioned moving center of gravity refers to the generalized center of gravity in addition to gravity acceleration and other accelerations generated when the object moves, or may be referred to as the center of inertia. The moment when the head main body 122 hits the golf ball, the center of gravity of the movement of the head main body 122 is shifted to a specific position (hereinafter referred to as an offset position). The hitting line 122a may be set adjacent to or located at the specific position, so that the hitting point corresponds to the center of gravity of the head body 122, so that the user can hit the ball accurately.

The sensor 124 in this embodiment is, for example, a gravity sensor (G-sensor), a gyroscope (Gyro Meter), or other appropriate types of dynamic sensors. The sensor 124 is disposed on the head main body 122 and is used for sensing dynamic information such as the displacement trajectory, acceleration, speed, and center of gravity position of the head main body 122 when the user swings the golf putter 100. The user can adjust his or her swing movement based on the dynamic information of multiple swings to improve the performance of the ball. Furthermore, during the swing, the head 120 is the largest turning radius of the entire golf putter 100 and has the largest amount of displacement per unit time. Therefore, the sensor 124 disposed on the head main body 122 can Get high-resolution dynamic information in time, making it have good sensing accuracy.

In this embodiment, the line of sight 122 a is formed on a surface 122 b of the head body 122, and a reference plane P (virtual plane in space) is perpendicular to the surface of the head body 122. 122b, the boundary between the reference plane P and the surface 122b of the head body 122 coincides with the line of sight 122a, and the center of mass C (labeled in FIG. 3) of the sensor 124 is not located on the reference plane P. In addition, a grip portion 112 (shown in FIG. 1) of the shaft 110 and the center of mass C of the sensor 124 are located on the same side of the reference plane P. That is, the direction of the center of mass C of the sensor 124 toward the grip portion 112 of the shaft 110 is deviated from the offset position of the head body 122 (that is, the position to which the center of gravity of the head body 122 is shifted to when swinging) (Also referred to as the position of the center of gravity of the head body 122 during the swing) and deviates from the line of sight 122a. In this embodiment, the offset position is, for example, located at the position of the hitting line 122a. However, in other embodiments, the offset position may be adjacent to but not at the position of the line of sight 122a. This is not restricted.

During the swing process, since the mass points at different positions of the sensor 124 will have different centripetal accelerations due to different distances from the center of rotation of the swing (the farther away from the center of rotation, the greater the centripetal acceleration), and The position of the moving center of gravity is related to the acceleration of each of its mass points, so the moving center of gravity of the sensor 124 will also be shifted in the direction D away from the swinger due to the swing motion. The moving center of gravity shift phenomenon can be inferred based on the definition of the center of gravity of physics, and is not described in detail here. In order to avoid the unexpected shift of the center of gravity of the head 120 due to the shift of the center of gravity of the sensor 124, the center of mass C of the sensor 120 is configured to deviate toward the holding portion 112 as described above. At the offset position and the line of sight 122a, the moving center of gravity of the sensor 124 may be shifted to the offset position or just to the offset position (such as a stroke Position of the ball sight line 122a) and coincide with the center of gravity of the club head body 122 to maintain the center of gravity of the overall movement of the club head 120 adjacent to or at a position corresponding to the offset position, so that the sensor 124 can Accurate dynamic sensing is performed when the center of gravity of the club head 120 is affected.

The relative positional relationship between the sensor 124 and the line of sight 122a shown in FIG. 1 to FIG. 3 is merely an example, and the present invention is not limited thereto. In other embodiments, the sensor 124 and the shot line of sight 122 a may have other appropriate relative positional relationships to deviate the sensor 124 from the line of sight 122 a. In addition, the golf putter 100 shown in FIG. 1 to FIG. 3 is, for example, a right-handed stick (its swing direction is from the right to the left of the swinger), but the novel creation is not limited thereto. In other embodiments, the It can be a left-handed stick (its swing direction is from the swinger's left to right).

The sensor 124 in this embodiment is, for example, detachably fixed to the head body 122. In this configuration, the golf putter 100 is, for example, a golf putter for practice. The user can use the golf putter 100 provided with a sensor 124 to practice and adjust according to the dynamic information sensed by the sensor 124 Self-swing action to improve the performance of using formal golf putts in official matches. The center of gravity allocation of the practice putt (ie, the golf putter 100) may be exactly the same as the center of gravity allocation of the formal golf putt, so that the dynamic information can be matched with the shot made by the formal golf putt. In other embodiments, the sensor 124 may be detachably disposed on the head body 122. In this configuration, the user can use the golf putter 100 equipped with the sensor 124 to practice and adjust his or her swing motion based on the dynamic information sensed by the sensor 124, and use the removal feeling The golf putter 100 of the tester 124 performs a formal game.

FIG. 4 is a schematic diagram of a signal transmitted from the sensor of FIG. 1 to an external device. In this embodiment, the sensor 124 may have a signal transmission unit 124a, and is adapted to transmit the sensed dynamic information S to a signal transmission unit 124a using Bluetooth transmission technology or other appropriate wireless transmission technology. The external device 50 allows a user to view the dynamic information S in real time through a display interface of the external device 50. The external device 50 is, for example, a portable electronic device such as a user's mobile phone, tablet computer, or notebook computer, and the present invention does not limit this.
